Shoulder replacement surgery involves removing a damaged or diseased shoulder joint and replacing it with an artificial joint (prosthesis). This procedure is commonly recommended for patients suffering from severe shoulder arthritis, rotator cuff tears, or shoulder fractures that do not respond to conservative treatments. The surgery can be performed as a total shoulder replacement, which replaces both the ball and socket of the shoulder joint, or a partial shoulder replacement, which only replaces one part of the joint. The goal is to relieve pain, restore shoulder function, and improve the patient’s quality of life.
